BACKGROUND

[0002] The present application relates to medical examination tables and,
more specifically, to medical examination tables that are designed for
optimizing access to a patient supported on the medical examination table
and also for optimizing the storage area near the medical examination
table.

[0003] Utilizing space within work areas is an area of importance in
designing equipment and devices. Also, it has become more and more common
for a single examination room to be used for different stages of a
medical examination. For instance it would be advantageous for a single
examination room to be used for an entire procedure, in a manner that is
efficient and comfortable for the patient. The initial review, where a
patient is typically sitting in a chair, and further examinations, where
a patient may have to lie upon a flat surface, preferably will happen in
the same room, thereby necessitating the need to store equipment and
devices for both procedures within the same examining room.

[0004] For instance, examination tables that have added storage areas as
part of the table have advantages over tables that do not have such
arrangements. Current tables still can be improved, particularly in
providing access to different storage areas on the examination table
during various examination steps.

[0005] Along with providing compact and more useful medical examination
tables, the tables should still be rigid and sturdy enough so that they
can be adequately used by a wide range of patients in a safe manner. For
instance, increasing storage area on the table, or increasing work area
for the doctor, in a manner that diminishes the amount of weight the
table may support or the range that the table may move, does not
necessarily result in a better table.

SUMMARY

[0006] One embodiment relates to a medical examination table, which
includes a seat, a compartment below the seat, a first extension, a
second extension, a lift mechanism, a base, and a storage section formed
in the base. The first extension is configured to be stored in the
compartment, and is further configured to project outward relative to the
seat when in an extended configuration of the first extension. The second
extension is configured to be stored in the compartment with the first
extension, and is further configured to project outward relative to the
first extension when in an extended configuration of the second
extension. The lift mechanism is configured to raise and lower the seat,
the compartment, and the first and second extensions. The base is coupled
to the lift mechanism. The storage section, formed in the base, is
disposed behind the seat, where an internal dimension of the compartment
is limited by the positioning of the storage section. Configuring the
first and second extensions in the extended configurations elongates the
medical examination table by a distance greater than the internal
dimension of the compartment.

[0007] Another embodiment relates to a medical examination table, which
includes a support structure, a first extension, and a second extension.
The first extension has a first surface, a pan, a portion defined in the
first surface configured to receive the pan, and a first cushion
removably supported by the first surface above the pan such that removing
the first cushion provides access to the pan. The first extension is
configured to project outward relative to the support structure when in
an extended configuration of the first extension, elongating the medical
examination table. The second extension has a second surface and a second
cushion thereon, where the second surface is contoured along a side
thereof to avoid interference with the pan. The second extension is
configured to project outward relative to the first extension when in an
extended configuration of the second extension, further elongating the
medical examination table.

[0008] Yet another embodiment of the invention relates to a medical
examination table, which includes a support structure, a first extension,
and a second extension. The first extension is configured to project
outward relative to the support structure when in an extended
configuration of the first extension, elongating the medical examination
table. The second extension is configured to project outward relative to
the first extension when in an extended configuration of the second
extension, further elongating the medical examination table. The first
extension is further configured to translate relative to the patient
surface and the second extension is further configured to translate
relative to the first extension.

[0009] Alternative exemplary embodiments relate to other features and
combinations of features as may be generally recited in the claims.

DETAILED DESCRIPTION

[0045] Referring generally to the FIGURES, a examination table and
components thereof are shown according to exemplary embodiments. The
examination table, shown as a medical examination table 10, utilizes the
space in and around the table in an effective and efficient manner for
storage and/or support of various articles (e.g., supplies, equipment,
instrumentation, components, etc.) while providing a table that is
suitable for use in a number of different procedures or applications
(e.g., examinations, surgical procedures, etc.). The table 10 generally
comprises a patient support 30 that is selectively movable (e.g.,
configurable, reconfigurable, adaptable, adjustable, etc.) between a
range of positions. The table 10 further comprises a first base 33 and a
lift mechanism (shown as a linkage system 12). The first base 33 supports
or otherwise assists in stabilizing the patient support 30, while the
lift mechanism is configured to selectively move the patient support 30
between a range positions.

[0046] The patient support 30 moves independent or separate of the first
base 33 between a lowered position (e.g., retracted position, wheelchair
accessible position, etc.), shown in FIG. 1, and a raised position (e.g.,
elevated position, examination position, etc.), shown in FIG. 2, and may
also be configured to move independent or separate of the first base 33
between a substantially upright position (e.g., seated position, vertical
position, partially reclined position, etc.), shown in FIG. 2, to
function as a chair and a substantially horizontal position (e.g., table
position, fully reclined position, etc.) to function as a bed.

[0047] According to an exemplary embodiment, a structure (e.g., housing,
body, storage compartment, storage pod, module, etc.), shown as a rear
storage section 70, is provided closely adjacent or otherwise coupled to
the first base 33. The storage section 70 provides a storage area
suitable for supporting one or more articles related to the medical
procedure (e.g., supplies, equipment, instrumentation, etc.) or other
items that may be beneficial to store in an examination table. Similar to
the first base 33, the movement of the patient support 30 is independent
or separate of the storage section 70. For example, the first base 33 may
be configured to rest upon a ground surface without moving during the
operation of the table 10.

[0048] Before discussing the details of the table 10 and components
thereof, it should be noted at the outset that references to "front,"
"back," "rear," "upper," "lower," "right," and "left" in this description
are merely used to identify the various elements as they are oriented in
the FIGURES, with "front," "back," and "rear" being relative to a patient
seated in the patient support 30. These terms are not meant to limit the
element which they describe, as the various elements may be oriented
differently in various applications.

[0049] It should further be noted that for purposes of this disclosure,
the term "coupled" means the joining of two members directly or
indirectly to one another. Such joining may be stationary in nature or
moveable in nature and/or such joining may allow for the flow of fluids,
electricity, electrical signals, or other types of signals or
communication between the two members. Such joining may be achieved with
the two members or the two members and any additional intermediate
members being integrally formed as a single unitary body with one another
or with the two members or the two members and any additional
intermediate members being attached to one another. Such joining may be
permanent in nature or alternatively may be removable or releasable in
nature.

[0050] Referring initially to FIGS. 1 through 3, the patient support 30 is
shown as generally including a patient support structure 32 (e.g.,
patient support surface, table, chair, bed, etc.) and a second base 34
(e.g., body, support structure, housing, platform, storage compartment,
etc.). According to the embodiment illustrated, the patient support
structure 32 includes a backrest, shown as a seat back 26, and a seat,
shown as a seat bottom 28. The seat back 26 is configured to support the
back, neck and/or head of a typical patient, while the seat bottom 28 is
sized and dimensioned to support the buttock and/or upper leg of a
typical patient. The seat bottom 28 is at least partially defined by a
first lateral side, shown as a right side 21, a second lateral side,
shown as a left side 23, a front portion 25 (e.g., region, edge,
periphery, etc.), a rear portion 27, and a seating surface 29.

[0051] The seat back 26 is shown as being a separate from the seat bottom
28. According to various alternative embodiments, the seat back 26 may be
integrally formed with the seat bottom 28 to provide a single unitary
body. According to still further alternative embodiments, the patient
support 30 may be divided into sections other than a seat back portion
and a seat portion. For example, the patient support 30 may include a
section specifically designed to support the head and/or neck of a
patient (e.g., a headrest, etc.) or a section specially designed to
support the lower leg or foot of a patient (e.g., a footrest, etc.).

[0052] As stated above, the patient support 30 moves between a lowered
position and a raised position. According to an exemplary embodiment,
when the patient support 30 is moved to the lowered position, the seating
surface 29 of that seat bottom 28 is at a height that allows for the
efficient and relatively easy transfer of a patient in a wheelchair to
the seating surface 29 and the return transfer of the patient from the
seating surface 29 to the wheelchair. For purposes of the present
application, such a height is referred to broadly as a wheelchair
accessible height.

[0053] The wheelchair accessible height is a height at which the seating
surface 29 of the seat bottom 28 is substantially coplanar with a seating
surface of a typical wheelchair (or slightly above or below depending on
whether the patient is entering or exiting the patient support 30). At
this height a patient can be readily slid from one seating surface to the
other. What constitutes a wheelchair accessible height will vary
depending on the size of the wheelchair. According to an exemplary
embodiment, the seating surface 29 of the seat bottom 28 is at least
lowerable to a height that is approximately 24 inches above the ground.
According to another exemplary embodiment, the seating surface 29 of the
seat bottom 28 is at least lowerable to a height that is approximately 18
inches above the ground. According to various alternative embodiments, it
may be beneficial to have the seating surface 29 of the seat bottom 28
lowerable to heights above and/or below those heights provided above to
accommodate a particular wheelchair.

[0054] While the wheelchair accessible height has been defined above with
reference to accommodating the transfer of a wheelchair bound patient to
and from the patient support 30, such a height may also benefit a
non-wheelchair patient attempting to enter or exit the patient support
30. For example, the wheelchair accessible height may assist an elderly
patient, an obese patient, or any other patient who may otherwise have a
mobility deficiency making it difficult to enter or exit the patient
support 30. Lowering the seating surface 29 to a wheelchair accessible
height advantageously reduces the likelihood that a separate foot step
will need to be used by such patients when exiting or entering the
patient support 30.

[0055] The patient support 30 is also movable to a raised position. When
the patient support 30 is in the raised position, the seating surface 29
of that seat bottom 28 is at a height that allows for the effective
examination of a patient by the examiner or caregiver. For purposes of
the present application, such a height is referred to broadly as an
examination height. According to an exemplary embodiment, the seating
surface 29 of the seat bottom 28 can be raised to at least a height that
is approximately 30 inches above a ground surface. According to another
exemplary embodiment, the seating surface 29 of the seat bottom 28 can be
raised to at least a height that is approximately 37 inches above a
ground surface. According to various alternative embodiments, it may be
beneficial to allow the seating surface 29 of the seat bottom 28 to be
raised to a maximum height that is above and/or below those heights
provided above.

[0056] According to an exemplary embodiment, the seat back 26 is pivotally
supported relative to the seat bottom 28 thereby allowing the inclination
or angle of the seat back 26 to be selectively adjusted relative to the
seat bottom 28. The seat back 26 can be configured to move between any of
a number of ranges relative to the seat bottom 28 depending on various
design criteria. According to the embodiment illustrated, the seat back
26 is configured to rotate relative to the seat bottom 28 between a
substantially upright position, shown in FIGS. 1 and 2, and a
substantially horizontal position, shown in FIG. 3. The rear edge 27 of
the seat bottom 28 substantially represents the axis at which the seat
back 26 rotates relative to the seat bottom 28.

[0057] To facilitate movement of the seat back 26 relative to the seat
bottom 28 a tilt mechanism is provided. Referring to FIG. 5, the tilt
mechanism is shown as a strut 86 that is centrally located relative to
the seat back 26. The strut 86 includes a first end 83 pivotally coupled
relative to the seat bottom 28 and a second end 85 pivotally coupled to
one of the second base 34 and the seat bottom 28. The strut 86 is
operably coupled to an activation device (shown as an actuator 20 in FIG.
19) which provides controlled movement for the seat back 26. The strut 86
acts as a gas spring or shock absorber for the seat back 26, thereby
allowing relatively smooth movement of the seat back 26 between various
positions. The actual structure of the strut 86 depends on whether the
table 10 is configured for manual or powered controls and may include any
electrical, mechanical or other device that assists in movement of the
seat back 26.

[0058] According to various alternative embodiments, any of a number of
known or otherwise suitable mechanisms, either manual, powered or a
combination thereof can be used to facilitate the movement of the seat
back 26 relative to the seat bottom 28. For example, the tilt mechanism
may be any of a variety of air, gas, liquid, elastomer, spring, or
hydraulic devices, shocks, or shock absorber, dashpot mechanisms, air
spring, cylinders, actuators that can selectively move the seat back 26.

[0059] Referring back to FIGS. 1 through 3, the patient support 30 further
includes the second base 34. The second base 34 supports the patient
support structure 32, and more specifically, supports the seat bottom 28.
The second base 34 moves with the seat bottom 28 as the patient support
30 is moved between the lowered position and the raised position.
According to an exemplary embodiment, the second base 34 provides one or
more storage areas suitable for supporting a variety of articles, and may
further be configured to support one or more auxiliary components of the
table 10. For example, as detailed below, the second base may be
configured to support a variety of auxiliary components such as a work
surface 64, or one or more support arms, shown as a pair of grab bars 38,
that further act as arm rests for a person sitting on the patient support
structure 32.

[0060] According to an exemplary embodiment, the second base 34 is shown
as a box-like structure disposed under the seat bottom 28. The size of
the second base 34 is maximized and extends substantially to the
periphery of the seat bottom 28 (e.g., laterally side-side and in a
longitudinally front-to-back, etc.). Increasing the size of the second
base 34 increases the available storage therein. However, limiting the
size of the second base 34 to the boundaries of the seat bottom 28 may be
both aesthetically pleasing (since the second base 34 is substantially
concealed when looking down from the seat bottom 28) and functional
(e.g., improves a caregiver's clearance around the table 10, provides for
a more compact table, etc.). According to various alternative
embodiments, the second base 34 may only take up a portion of the space
available under the seat bottom 28 (e.g., in a lateral direction and/or
in a longitudinal direction, etc.) and/or may outwardly extend from at
least one side of the seat bottom 28.

[0061] The height of the second base 34 may vary depending upon a number
of factoring including the desired height of the seating surface 29 of
the seat bottom 28 in the lowered position. According to an exemplary
embodiment, the second base 34 has a height of approximately 10 inches to
approximately 18 inches. According to alternative embodiments, the height
of the second base 34 may be greater or less than 10 inches or 18 inches.

[0062] Referring to FIG. 4, the second base 34 provides a storage area,
shown as a front storage area 40, that is accessible from a front side of
the second base 34. The front storage area 40 comprises a drawer, shown
as a removable storage bin 42. The storage bin 42 allows a user to
maximize the overall storage area of the table 10, which further enhances
the overall utility of the table 10. According to an exemplary
embodiment, the storage bin 42 is a relatively large or oversized
receptacle extending in a longitudinal direction between a front side of
the second base 34 and a rear side of the second base 34 and in a lateral
direction between a left side of the second base 34 and a right side of
the second base 34. Providing a storage receptacle of such size may
advantageously allow the receptacle to be used to store any of a number
of items. The storage bin 42 is also easily removed when necessary for
cleaning and the like, and may include a stop mechanism (not shown) to
reduce the likelihood that the storage bin 42 may be inadvertently
removed from the front storage area 40. A heating element may be provided
on or near storage bin 42 to heat the contents thereof. An indicator
light 46 may be configured to indicate when the heating element is in
operation (light on) or not in operation (light off). In one embodiment,
indicator light 46 may be part of an on/off switch configured to turn on
or off the heating element.

[0063] Referring to FIG. 10, the storage bin 42 may be divided or
partitioned into compartmentalized storage areas to provide for improved
organization or for the efficient use of the storage space. To facilitate
the division or partition of the storage bin 42 into compartmentalized
storage areas, one or more dividers are provided. According to the
embodiment illustrated, the storage bin 42 is configured to receive a
plurality of multi-configurable partitions or dividers 56 that are
secured within slots 58 located on the sidewalls of the storage bin 42
and can be added or removed relatively easily and quickly. The dividers
56 may be arranged to divide and compartmentalize the storage bin 42
according to an individual's needs or preferences. By allowing a more
efficient and easier manner of organizing materials, the table 10
provides a useful storage space.

[0064] The front storage area 40 also comprises additional space that can
accommodate a device, pan, and/or an extension 44 (e.g., leg support,
head support), which may support a tray. Referring to FIG. 11, the
extension 44 is shown having a downward hanging arm 60 that comes in
contact with a stop 62. The extension 44 should be considered broadly to
include a wide range of devices and designs, such as, but not limited to,
padded surfaces, urology pans, storage devices, or other related
containers. The hanging arm 60 and the stop 62 prevent the extension 44
from being inadvertently removed when the extension 44 is pulled out to
be accessed. However, if the extension 44 needs to be removed, possibly
for cleaning or being replaced with a different device or component, FIG.
12 shows how this is accomplished. The hanging arm 60 is pivotally
attached to the extension 44. When removal is necessary, the arm 60 is
moved to either the left or right and can be moved past the stop 62 and
removed. A heating module (not shown) may be installed on the second base
34 to warm the extension 44, or tray supported by the extension 44.
Stirrups 48 are also located in the front storage area 40 without
impeding movement of the storage bin 42 and the device 44, while still
being able to be stored away when not in use.

[0065] FIG. 26 shows the second base 34 according to another exemplary
embodiment. In such an embodiment, the second base 34 includes a storage
area accessible from at least one of the lateral sides of the second base
34. Such a storage area is shown as a side storage area 41. Similar to
the front storage area 40, the side storage area 41 is shown as receiving
a drawer, shown as the removable storage bin 42. For such an embodiment,
the storage bin 42 may be configured as drawer as described above or as a
pass-through drawer that is detailed below that would be accessible from
both lateral sides of the second base 34.

[0066] It should be noted that the front storage area 40 and the side
storage area 41 may have storage configurations other than those suitable
for receiving a drawer. For example, either one of the front storage area
40 and the side storage area 41 may include one or more shelves, cabinets
doors, storage racks, or any other suitable storage configuration.

[0067] Referring to FIGS. 13 and 14, the second base 34 is further shown
as supporting a platform, shown as the work surface 64. The work surface
64 advantageously provides a surface for the medical practitioner that
can be useful for writing or for placing instruments upon. The work
surface 64 is coupled relative to the seat bottom 28 and may be supported
at a variety of positions relative to the seat bottom 28. For example,
the work surface 64 may be supported relative to a front end of the seat
bottom 28, a right side 21 of the seat bottom 28, a left side 23 of the
seat bottom 28, and/or combinations thereof. According to an exemplary
embodiment, the work surface is coupled to at least one of the seat
bottom 28 and the second base 34, but in alternative embodiments may be
coupled to another structure and supported adjacent to the seat bottom
28.

[0068] According to an exemplary embodiment, the work surface 64 is
configured to be selectively moved between a stowed or retracted position
and a use position. In the use position, the work surface 64 is generally
supported closely adjacent to the seat bottom 28 and may be provided at a
height that is similar to the height of the seating surface 29. According
to an exemplary embodiment, the work surface 64 is stowed under the
patient support surface 32 and is moved to the use position when desired.
According to various alternative embodiments, the work surface 64 may
collapsible and/or pivotally coupled relative to the seat bottom 28 such
that it is stowed without being stowed under the seat bottom 28. For
example, the work surface 64 could be folded away, such as along the side
or back of the second base 34.

[0069] According to the embodiment illustrated, the work surface 64 is
slidably coupled to the second base 34 and located below the seat bottom
28. The work surface 64 may be configured to slide out relative to one or
more of the lateral sides of the seat bottom 28. As shown by the arrows,
the work surface 64 in the embodiment illustrated can be pulled out from
either direction, thereby accommodating right- and left-handed persons
and accommodate the examiner on either side of the table 10. Having the
work surface 64 stored on the table 10 and accessible from either side of
the seat bottom 28 advantageously improves the effectiveness and/or
usefulness of the table 10 within the examination room.

[0070] According to an exemplary embodiment, the work surface 64 is
designed so that it will not be inadvertently removed from the table 10.
As shown in FIG. 14, the outside edges of the work surface 64 rest within
channels 66 that allow the work surface 64 to slide back and forth.
Grooves 67 are located on the underside of the work surface 64, which
allow the board 64 to slide over a pair of bumpers 68, located on
oppositely disposed corners of the upper surface 37 of the second base
34. Thus, the work surface 64 will only be pulled out until the end of
one the grooves 67 comes in contact with a corresponding bumper 68. The
bumpers 68 or other similar devices may be removed when necessary, to
accommodate cleaning of the work surface 64. For example, the bumpers 68
could be threadably engageable with the upper surface 37 and unthreaded
when cleaning is necessary, or possibly the bumpers 68 could be
depressable to allow the work surface 64 to slide over the bumpers 68.

[0071] Referring to FIGS. 1 and 2, the second base 34 is further
configured to support the grab bars 38. The grab bars 38 may be used by
patients for support when on the patient support structure 32, for
assistance onto and off of the patient support structure 32, and/or for
assistance when repositioning themselves on the patient support structure
32. The grab bars 38 further act as bed rails to help prevent a person
from rolling off of the patient support structure 32 when the patient
support structure 32 is fully reclined to form a bed. The grab bars 38
are designed to provide multiple grab points for a patient, thereby
accommodating a wide range of patients. The grab bars 38 extend outwardly
to the front of the seat bottom 28, which aids patients in properly
positioning and orientating themselves on the patient support structure
32.

[0072] The grab bars 38 are designed in a manner so that clearance is
provided for the work surface 64 (if provided) when the work surface 64
is in a use or extended position. More specifically, the grab bars 38 are
designed such that the medical practitioner may be utilizing the benefits
of the work surface 64, while a patient supported on the patient support
structure 32 is simultaneously utilizing the benefits of the grab bars
38. Referring back to FIG. 13, the work surface 64 is designed to slide
under the grab bar 38 when moved between a stowed and use position.

[0073] Referring further to FIGS. 1 and 2, the grab bars 38 act as arm
rests and/or bed rails for the patient support structure 32 depending on
the position of the patient support 30. The grab bars 38 are configured
to be selectively moved between a first position (e.g., an arm rest
position, chair position, etc.) and a second position (e.g., a bed rail
position, bed position, etc.). The first position is shown as being
substantially 180 degrees offset from the second position. According to
an exemplary embodiment, the grab bars 38 are configured to be rotated
between the first position and the second position while remaining
coupled to the second base 34.

[0074] As detailed below, the grab bars 38 are also configured to be
selectively moved to a third position (e.g., release position, removal
position, etc.), the third position being located somewhere between the
first position and the second position. The grab bars 38 can also be
moved to any of a number of intermediate positions between the first
position and the second position to accommodate the needs of the patient
and/or the medical practitioner conducting the examination. For example,
the grab bars 38 may be moved to a position that allows a patient to
enter or exit the patient support 30 from the side. This may be useful
when transferring a wheelchair patient to or from the patient support 30.

[0075] FIGS. 6 through 7A show the grab bars 38 according to an exemplary
embodiment. FIG. 6 depicts the grab bar 38 as associated with FIG. 1 and
FIG. 7 depicts the grab bar 38 as associated with FIG. 3. It should be
noted that movement (e.g., rotation, etc.) of the grab bar 38 is
independent of the movement of the patient support 30. According to
various alternative embodiments, the movement of the grab bars 38 may be
coupled to the movement of the patient support 30. For example, the grab
bars 38 may be configured to move towards the first position when patient
support 30 is moved to the substantially upright position.

[0076] According to the embodiment illustrated, each grab bar 38 has a
shaft 50 that is pivotally inserted into a mount 52. The shaft 50 and the
mount 52 are designed to prevent inadvertent removal of the grab bars 38.
A protrusion 50a located on the shaft interacts with a slot 52a on the
mount. This allows only selective removal of the shaft 50 from the mount
52.

[0077] When the grab bar 38 is in a support position (as shown in FIG. 6),
the shaft 50 is locked within the mount 52 and may not be removed. Not
only does this prevent the grab bar 38 from being improperly removed from
the table 10, it also insures that the grab bar 38 will not move
unnecessarily when a person needs extra support getting onto and off of
the table 10. The grab bar 38 may only be removed when it has been moved
from a support position (i.e., any position between the first position
and the second position) to the third or removal position. According to
an exemplary embodiment, the removal position is angularly offset
approximately 90 degrees from the first position and/or the second
position. According to various alternative embodiments, the removal
position may be at an angle other than 90 degrees and may be at an angle
outside of the first position and/or the second position.

[0078] As shown in the drawings, and particularly in FIG. 7A, the mount 52
is shown having two slots 52a. As shown, the protrusion 50a will only
interact with the upper slot. The mount 52 is designed with two slots 52a
so that the same mount 52 can be used for both the left and the right
side of the table, thereby simplifying the assembly and manufacture of
the table. The slot 52a in FIG. 7A is shown to extend through and across
the mount 52. This arrangement would be suited for when the grab bars 38
would also be rotated 180 degrees for use as guard rails when the support
structure 32 is in a bed-like position. According to another embodiment,
the female/male arrangement of the shaft 50 and the mount 52 could be
reversed.

[0079] According to another exemplary embodiment, the grab bars 38 can be
designed and arranged so that they will be prevented from rotating
completely 180 degrees between the first position and the second
position. This may prevent the grab bars 38 from interfering with the
movement various rear storage compartments when the table 10 is in a
position as shown in FIG. 1. However, such an arrangement will still
allow easy access for a patient and the grab bars 38 will still assist a
person in getting on and off of the table 10.

[0080] The second base 34 may also support a device for adjusting the tilt
of the seat bottom 28. Referring to FIGS. 4, 14, and 4A, a pelvic tilt
device 49 is shown according to an exemplary embodiment. The pelvic tilt
device 49 further allows the table 10 and the patient support structure
32 to be repositioned as necessary. The tilt device 49 is shown as
comprising an adjustable bar that can be locked thereby placing the seat
bottom 28 in a tilted position and be released when the tilt position is
not needed. According to various alternative embodiments, any of a number
of suitable tilt mechanisms may be used to tilt the positioning the seat
bottom 28 relative to the second base 34. It should be noted that even
with the seat bottom 28 tilted by the tilt device 49, the seat back 26 is
still considered to be substantially horizontal with the seat bottom 28
when moved to the bed-like position.

[0081] To support the patient support 30 and the various components
thereof, the first base 33 is provided. Referring to FIGS. 2 and 15
through 18, the first base 33 is shown as comprising a first structure
(e.g., horizontal support, footprint, etc.), shown as a support extension
36, and a second structure (e.g., vertical support, etc.), shown as a
wall 35. The support extension 36 outwardly extends from the wall 35 in a
direction that is substantially perpendicular to the wall 35 and in such
a direction that the support extension 36 is provided under the seat
bottom 28 and second base 34 of the patient support 30. The support
extension 36 is shown as a substantially continuous member, but
alternatively may be provided as discontinuous structure (e.g., a pair or
prongs or forks outwardly extending from a bottom edge of the wall 35.

[0082] The wall 35 upwardly extends relative to the support extension 36
and is defined at least in part by a front surface 51. The front surface
51 may be a substantially linear surface, a curvilinear surface, or
include both linear and curvilinear portions. According to the embodiment
illustrated, the front surface 51 is a substantially vertical surface.
Configuring the front surface 51 in this manner may provide clearance for
the movement of the seat bottom 28 and the second base 34.

[0083] The first base 33 may be suitable for supporting the patient
support 30 without requiring the assistance of any other structure (e.g.,
rear storage section 70). According to an another embodiment, the first
base 33 may not include the support extension 36 or an equivalent
thereof. Rather the rear storage section 70 (detailed below) or the wall
35 may be adequately weighted and configured to support the patient
support 30.

[0084] To facilitate the movement of the patient support 30 between the
lowered position and the raised position, the lift mechanism is provided.
The lift mechanism is coupled between the first base 33 and the patient
support 30 and is configured to move the patient support 30 without
moving the first base 33. According to an exemplary embodiment, the lift
mechanism comprises a linkage system 12 for moving the patient support
30. The linkage system 12 allows the patient support 30 to be easily
moved between a wide range of heights, and allows the patient support 30
to move separately and independently from the storage section 70.

[0085] Referring to FIGS. 15 through 18, the linkage system 12 comprises
one or more links or bars, referred to collectively with the reference
numeral 14, and one or more actuators, referred to collectively with
reference numeral 16. According to an exemplary embodiment, the linkage
system 12 comprises four bars, two parallel upper bars 14a and two
parallel lower bars 14b, which provide stability for the table 10 over a
wide range of weights. The upper bars 14a and the lower bars 14b each
include a first end pivotally coupled to the first base 33 and a second
end pivotally coupled to the second base. The upper bars 14a are each
coupled to a respective actuator 16. The actuator 16 extends through or
from a plane of the front surface 51 of the first base 33 with a first
end pivotally coupled to the first base 33 and a second end pivotally
coupled to the patient support 30, and more specifically, to the upper
bar 14a.

[0086] The actuator 16 is configured to move between a retracted position
(shown in FIG. 16) and an extended position (shown in FIG. 18). When the
actuator 16 is in the extended position, the patient support 30 is in the
raised position. When the actuator 16 is in the retracted position, the
patient support 30 is in the lowered position. In both the lowered
position and the raised position, the seat bottom 28 of patient support
30 is supported so that the seating surface 29 defines a substantially
horizontal plane. The arrangement of the link bars 14a, 14b and the
actuator 16 allow the seat bottom 28 to be lifted between the lowered
position and the raised position while keeping the plane defined by the
seating surface substantially fixed through at least a portion of the
range of movement of the seat bottom 28. According to the embodiment
illustrated, the linkage system 12 lifts the seat bottom 28 while keeping
the plane of the seat surface 29 fixed in a substantially horizontal
plane during the entire range of movement.

[0087] According to an exemplary embodiment, the actuator 16 is a
push-only actuator designed to lift the patient support 30 when moved to
an extended position. As a push-only actuator, the actuator 16 relies on
gravity alone to move or return the actuator 16 to a retract position.
The other actuators 16 used throughout the table 10 may also be push-only
actuators. Using push-only actuators may reduce the likelihood that the
table 10 will be damaged from being driven down on an object (e.g., a
stool 8, etc.).

[0088] According to various alternative embodiments, the lift mechanism
may any of a variety of known or otherwise suitable devices including,
but not limited to, a scissor-lift, a chain drive, a rack and pinion,
hydraulic cylinders, castings, or other devices. According to a further
alternative embodiment, a second lift system may be provided so that the
rear storage section 70 (detailed below) is also movable, which may
enhance the usefulness of the table.

[0089] FIGS. 22 and 23 show a shroud 88 (e.g., cover, shield, close-out
device, etc.) that generally covers the linkage system 12 to shield or
otherwise conceal the linkage system 12. The shroud 88 may extend over a
top portion of the linkage system 12 and/or over a side portion of the
linkage system 12. The shroud 88 may also conceal or interact with a pair
of switches or blades 90 (one on each side of the second base 34) having
sensors coupled thereto as part of the object detection system. Such
sensors, when activated, may restrict the movement of the patient support
30. For example, a slight gap is located between the second base 34 and
the first base 33 near the shroud 88. If this gap is reduced, such as by
coming into contact with an object, sensors or switches coupled to the
blades 90 will restrict further movement of the patient support 30.

[0090] Provided rearward of the first base is the rear storage section 70
providing a rear storage area. As noted above, the rear storage section
70 is suitable for supporting one or more articles related to the medical
procedure (e.g., supplies, equipment, instrumentation, etc.). Referring
to FIGS. 8 and 9, the rear storage section 70 is shown as a box-like body
or cabinet 76. Similar to the first base 33, the movement of the patient
support 30 is independent or separate of the cabinet 76. In other words,
the linkage system 12 can move the patient support 30 between the lowered
position and the raised position without lifting the cabinet 76. Such a
configuration may advantageously allow storage areas of the table 10 to
remain accessible to a medical examiner or caregiver regardless of the
position of the patient support 30.

[0091] The cabinet 76 is at least partially defined by a top surface 72, a
back surface 80, a first lateral side surface, shown in FIG. 1 as a right
side surface 73, and a second lateral side surface, shown as a left side
surface 75. The top surface 72 is a substantially flat surface that can
be used for supporting objects upon when the patient support structure 32
is in the substantially upright position (i.e., a chair position). As
detailed below, the table 10 may include a system designed to reduce the
likelihood that objects placed upon the top surface 72 will be damaged or
crushed in the event that the patient support structure 32 is moved into
another position.

[0092] According to an exemplary embodiment, the top surface 72 also
functions as a lid or cover for a storage area 74 (see FIG. 9), which can
be used for storage of items, such as paper rolls that cover the patient
support structure 32. According to various alternative embodiments, the
top surface 72 may be eliminated and the storage area may be exposed to
the ambient environment. However, providing the top surface 72 over the
storage area 74 conceals the storage area 74 and protects the storage
area 74 against the introduction of contaminants (e.g., dust particles,
spilled fluids, etc.). Use of the top surface 72 as a lid allows the
storage area 74 to remain concealed throughout the various movements of
the patient support structure 32. The storage area 74 will be exposed or
be accessible only when the medical examiner or caregiver selectively
opens the lid.

[0093] According to the embodiment illustrated, the top surface 72 is
pivotally coupled at a front edge of the cabinet 76. Coupling the top
surface 72 in this manner may allow the top surface to be at least
partially opened even when the seat back 26 is partially reclined. A
latch device 77 may be provided to support the top surface 72 in an open
position. According to various exemplary embodiments, the top surface 72
may take on any of a number of forms for providing a lid. For example,
the top surface 72 may be divided or segmented, with only a portion of
the top surface 72 functioning as a lid. Further, the top surface 72 may
be hinged to any edge or portion of the cabinet 76. Further still, the
top surface 72 may be configured to open in ways other than pivotal
movement (e.g., by sliding or retracting into a portion of the cabinet
76, etc.).

[0094] Referring further to FIGS. 8 and 9, the cabinet 76 is also
configured to house or support one or more drawers that may be accessible
from the right side 73 and/or the left side 75. According to the
embodiment illustrated, a pair of pass-through drawers 78 are received by
the cabinet 76. The drawers 78 are slidable through the cabinet 74
(between the right side 73 and the left side 75) and are easily
accessible on either side of the table 10. The drawers 78 are
substantially similar to the drawers discussed in U.S. Pat. No.
6,568,008, owned by the same assignee and incorporated by reference.

[0095] Movement of the drawers 78 does not interfere with the opening and
closing of the storage area 74. Further, as shown in FIG. 9, the drawers
78 may be opened or closed from either side of the table 10, and may also
be opened or closed concurrently. The drawers 78 may also be opened or
closed when the table 10 is any position. Thus, the table 10 provides
accessibility to the storage area 70 during any of several examination
procedures, which reduces the need for other storage areas in the room
that contains the table 10. Likewise, because the drawers 78 may be
opened from either side, the table 10 equally suits left- or right-handed
practitioners and provides more options of arranging the table 10 within
a small examination room. As shown in phantom in FIG. 8, a lock or other
device 79 can be used to prevent the drawers 78 from going completely
through, which is preferable if the table 10 is situated where access
from only one side of the table is warranted or desired.

[0096] Providing a storage area accessible to a medical practitioner along
a lateral side of the table 10 may optimize the location of an item for
use during the examination or procedure. The type of storage provided
along the lateral sides of the table 10 is not limited to the use of
drawers 78. For example, the cabinet 76 may include one or more shelves,
racks, cabinet doors concealing a storage compartment, or any other
suitable form of storage.

[0097] FIG. 5 shows a rear elevation view of the table 10 and the cabinet
76. According to the embodiment illustrated, the back surface 80 of the
cabinet 76 is configured to support the necessary electrical connections
82 to provide power for the table 10. Also located on the back surface 80
is an on/off switch 84 that allows a practitioner to turn off power for
movement of the table 10 when the practitioner leaves the room. The
placement of the switch 84 on the back surface 80 of the cabinet 76 is
also advantageous in that it can be activated or deactivated discretely
without alerting others in the room to the location of the switch 84. The
top surface 72 is also preferably designed to extend outward over switch
84, thereby further concealing the switch 84.

[0098] Referring to FIG. 25, the rear storage section 70 may alternatively
be provided with a storage area accessible from the rear surface 80.
Providing a storage area accessible to a medical practitioner at the rear
surface 80 may also optimize the location of an item for use during the
examination or procedure. The type of storage provided along the rear
surface 80 may be any of a variety of suitable storage arrangements. For
example, the cabinet 76 may include one or more shelves, racks, cabinet
doors concealing a storage compartment, or any other suitable form of a
storage arrangement. According to the embodiment illustrated, the storage
area is configured to receive a drawer 81 that can be opened or closed
when the patient support 30 is any position.

[0099] According to an exemplary embodiment, the rear storage section 70
is coupled to the rear side of the first base 33. The rear storage
section 70 may be fixedly coupled to the first base 33, or alternatively,
may be movably and/or detachably coupled to the first base 33. The rear
storage section 70 may be integrally formed with the first base 33 to
provide a single unitary base or may be separate component that is
selectively added to the table 10. To facilitate the coupling of the rear
storage section 70 to the first base, any of a number of suitable
techniques may be used including, but not limited to, mechanical
fasteners (e.g., bolts, rivets, clips, brackets, clamps, etc.), a
suitable welding process, an adhesive, etc.

[0100] According to another exemplary embodiment, the rear storage section
70 may be configured as a storage module or pod that is selectively added
to the first base 33. These storage modules or pods may having varying
storage configurations and/or sizes, each be interchangeable with the
first base 33. Such an embodiment may allow examination tables to be
supplied the same first base 33 and patient support 30, but with varying
rear storage configurations.

[0101] According to another exemplary embodiment, the rear storage section
70 may be positioned closely adjacent to the first base 33 without being
coupled to the first base 33. For such an embodiment, the first base 33
is configured to support or otherwise stabilize the patient support 30 as
it moves between the various positions without the assistance of the rear
storage section 70.

[0102] As noted above, the table 10 may include one or more systems (e.g.,
an object detection systems, etc.) designed to restrict the movement of
the patient support 30 in the event that an object is placed within the
path of movement of the patient support 30. Referring to FIGS. 19 through
21, when the table 10 is repositioned between the substantially upright
position (i.e., a chair-like position) and the substantially horizontal
position (i.e., a bed-like position), there is potential for the patient
support 30 to be inadvertently driven into the rear storage section 70 or
another object placed upon the top surface 72 of the rear storage section
70.

[0103] It should be noted that according to an alternative embodiment, the
table 10 may designed so that the patient support 30 can move
automatically between the chair-like and bed-like positions without
manually needing to navigate the patient support 30 over and around the
rear storage section 70, it may also be possible that the separate parts
of the patient support 30 move individually. That is, the seat back 26
may move independently from the seat bottom 28 and, also, independently
from the overall movement of the patient support 30.

[0104] Referring back to FIGS. 19 through 21, the patient support 30 is
shown in a chair-like position. If the seat back 26 is reclined
independently from the seat bottom 28, the seat back 26 may be driven
into the rear storage section 70, which could possibly cause damage to
either the rear storage section 70 or the patient support 30. To reduce
the likelihood of such damage, an object detention system may be
provided.

[0105] According to an exemplary embodiment, the table 10 further
comprises a cover 18 located on the back of the seat back 26. One or more
sensors or switches 22 are operably coupled between the cover 18 and the
seat back 26. There is a slight gap between the cover 18 and the seat
back 26. When the cover 18 comes into contact with an abutting surface
(e.g., a surface of rear storage section 70), the cover will move inward
thereby activating at least one of the sensors or switches 22 and causing
the movement of the seat back 26 and/or patient support 30 to cease.

[0106] FIG. 19 shows the seat back 26 with the cover 18 removed. Located
on the seat back 26 are a plurality of sensors or switches 22, that when
activated, are designed to restrict the movement of patient support 30.
The sensors or switches 22 are electrically coupled to the circuitry and
the controls of the table 10. According to the embodiment illustrated,
the sensors 22 are located at each of the four corners of the seat back
26 and cover 18. Such positioning is intended to detect unintended
contact and stop movement of the patient support 30 over a wide range of
angles and positions. The sensors or switches 22 are a push-in style
button or device and extend outwardly in a normal position toward the
cover 18. According to various alternative embodiments, any type of
sensing or detecting device may be used (e.g., motion, optical,
proximity, etc.) and any number of suitable sensors or switches may be
provided.

[0107] The cover 18 may come in contact with the rear storage section 70
or an object over the normal range of movements of the patient support
30. FIG. 21 shows the cover 18 coming into contact with the rear storage
section 70, which moves the cover 18 towards the seat back 26. At the
lower section of the seat back 26, the gap between the cover 18 and the
seat back 26 is eliminated. This forces a lower sensor or switch 22 to be
depressed and deactivates the electrical circuit controlling the movement
of the patient support 30, which prevents further movement of the seat
back 26.

[0108] FIGS. 22 and 23 show an additional object detection system. The
second base 34 of the patient support 30 is shown elevated over the
support extension 36. A plate 24 is suspended below the bottom of the
second base 34 and is movably attached to the second base 34 by a
plurality of fasteners, with a gap located between the second base 34 and
the plate 24. In FIG. 23, the patient support 30 is shown being moved
downward. The patient support 30 may come into contact with an object,
such as a stool 8 (shown in phantom), that could impede movement of the
patient support 30 and damage the table 10. Sensors 25, similar to the
sensors 22, are activated to prevent the movement of the patient support
30. In this situation, the plate 24 is pushed upward, closing the gap
between the plate 24 and the second base 34. The sensors 25 are thereby
depressed, which inhibits any further movement of the patient support 30
until the object is removed. If continuous contact is made with the
depressed sensors 25, the movement of the patient support 30 will reverse
upwards until the contact is removed. The sensors 22 could be designed to
do the same, as well.

[0109] Referring to FIG. 24, a perspective view of a control panel 92 is
shown according to an exemplary embodiment. According to the embodiment
shown, the control panel 92 is a foot-operated. Individual controls 94
and 96 can be used for up/down movement and inclined/declined movement,
respectively. A single pedal may be used for a table that has manually
operated backrest. The control panel 92 may also have an automatic reset
switch 98 to move the patient support 30 to a retracted chair-like
position, which can be considered the normal position for the table 10.
An emergency stop switch 100 may also be located on the control panel 92
to stop all movement when activated when the patient support is moving
from a first pre-set position to a second pre-set position under the
automatic control of a control circuit, actuation of any switch, or
control panel as may be configured to stop the movement. The control
panel 92 is designed to simplify use of the table 10. According to
various alternative embodiments, any of a number of control panels may be
used to operate the table 10 including, but not limited to, controls
provided on the structure of the table 10, hand-held controls, wireless
controls, and/or any other suitable type of controls.

[0110] According to an exemplary embodiment, the table 10 is run with a
low voltage electrical current, which provides a safer and more
economical table than previous table designs. In one particular
embodiment, the electrical current flowing through the actuators of the
table is approximately 24 volts or less, which may reduce potential risks
associated with higher voltage devices. The circuit may comprise any
digital and/or analog components (e.g., microprocessor,
application-specific integrated circuit, etc.) configured to control the
table using power from a power source or control signal from control
panel 92 and/or other input devices (e.g., touch screen display, speech
recognition module, etc.).

[0111] In operation, the patient support 30, and more specifically the
patient support structure 32, of the table 10 is configured to move
between different positions independent or separate of the first base 33
and any storage area coupled thereto or otherwise supported adjacent
thereto. For example, the patient support structure 32 is configured to
move between a substantially upright position and a substantially
horizontal position in addition to moving between a lowered position and
a raised position. This advantageously allows the top surface 72 to be
used to place and store objects and instruments (e.g., see FIG. 3), even
when the table 10 is acting as an examination bed. Further, as the
patient support 30 or patient support structure 32 moves throughout the
various positions, it does so without interfering with the rear storage
section 70. This not only provides more freedom in the movement of the
table 10, but does not compromise the potential storage area of the table
10. That is, the table 10 provides storage area in all positions, which
makes the table more useful for the medical examiner.

[0112] Referring again to FIG. 26, the medical examination table 10
includes the support structure 32, which in some embodiments includes the
seat 28 (e.g., seating area, seating surface) and seat back 26 (e.g.,
backrest). In one configuration, the seat back 26 is configured to
project upward from a rear portion of the seat 28, and is further
configured to recline backward relative to the seat 28 such that the seat
back 26 is horizontally aligned with the seat 28, forming a substantially
flat tabletop (see FIG. 3). In other embodiments, another patient support
structure includes a fixed, flat examination table surface, without
distinct seat and seat back portions. In some such embodiments, the table
surface moves vertically to accommodate receiving disabled, shorter, or
handicapped patients, while in other such embodiments the height of the
medical examination table surface is not adjustable.

[0113] According to an exemplary embodiment, the medical examination table
10 further includes a compartment 234 that may be generally located below
the seat 28 and formed in the second base 34. In some such embodiments,
the compartment 234 is configured to provide storage for one or more
medical items, such as stirrups 48 (FIG. 4), a storage area 40 (e.g.,
drawer), a pan 202 (e.g. pull-out debris pan) (FIG. 28), table space on a
surface 204 (FIG. 28), and an extension 44 (FIG. 4) for head or leg
support. In order to provide the seat 28 at a height convenient for
receiving a patient, the vertical height of the compartment 234 is
limited to a height of less than three feet, about two feet, etc., so
that the seat can be sufficiently lowered. In other contemplated
embodiments an open area is provided in place of the compartment 234
below the respective seat, where one or more medical items may be secured
to the underside of the seat and may retract into the open area for
storage.

[0114] According to an exemplary embodiment, the medical items of the
medical examination table 10 shown in FIG. 26 are engineered to fit
together within the compartment 234 in a highly-ordered and compact
manner. Dense and organized packaging of the medical items within the
compartment 234 is designed to facilitate patient comfort and efficient
examination procedures by pre-positioning particular medical items (e.g.,
pan 202, extension 44) in locations requiring less reorientation of the
patient on the examination table 10. For example, a patient need not
slide rearward on the medical examination table 10 for leg support.
Instead, the extension 44 may be pulled out from below the seat 28, in
some embodiments.

[0115] In some embodiments, the compartment 234 is rigidly coupled to the
seat 28 and is located directly below the seat 28. In other contemplated
embodiments, a compartment may be below, but separated from the
respective seat by one or more intermediate components or an open area.
In alternate embodiments a compartment, similar to the compartment 234
shown in FIG. 26, is formed below a medical examination table that does
not include a distinct seat, such as a stationary table having a fixed,
flat surface. In some such embodiments, the respective compartment may be
positioned below an end or side of the stationary table, in a location
designed to facilitate patient comfort and efficient examination
procedures.

[0116] Still referring to FIG. 26, in some embodiments the medical
examination table 10 includes the base 33 (e.g., first base, support
base), the storage section 70 (e.g., rear storage section), and a lift
mechanism 232 (FIG. 2), which may include the linkage system 12 in some
embodiments, hydraulic cylinders, motor-driven worm gears,
rack-and-pinion gears, pneumatic cylinders, or other actuators. The base
33 is designed to provide the lowermost support for the medical
examination table 10, interfacing with the floor, ground, etc. In some
embodiments, the base 33 includes the support extension 36 (FIG. 14A)
(e.g., toe board), which expands the footprint of the base 33. In some
such embodiments, the compartment 234 below the seat 28 need not
interface directly with the ground, and instead may be fully supported
while vertically separated from the ground in some configurations of the
medical examination table 10. Separation of the compartment 234 from the
ground may provide convenient leg room for a medical practitioner
examining a patient, as well as additional storage space, such as for a
stool (see FIG. 23), the belongings of the patient, or other items more
conveniently placed in close proximity to the patient and/or practitioner
during use of the medical examination table 10, facilitating a speedy and
efficient medical examination.

[0117] According to an exemplary embodiment, the storage section 70
includes drawers 78, which may provide useful and convenient storage for
items such as blankets, gowns, pieces of equipment, or supplies.
Integration of the drawers 78 with the medical examination table 10
allows for quick access to the items by the medical practitioner,
increasing the efficiency of examination procedures. However, in some
embodiments, the storage section 70 provides a rearward boundary to an
internal dimension of the compartment 234 below the seat 28, such as the
width or length of the compartment 234. Accordingly, items configured to
be stored in the compartment 234, such as the storage bin 42 (FIG. 10)
and extensions 44 and 206 (FIGS. 27-29) may be limited to structurally
conform to the internal dimension.

[0118] In some embodiments, the medical examination table 10 includes the
lift mechanism 232, which may be configured to raise and lower the seat
28 relative to the base 33, the compartment 234, and the contents thereof
(e.g., extensions 44 and 206). The seat 28 is configured to be lowered
relative to the base 33 by the lift mechanism 232 to a wheelchair
accessible height, facilitating the transfer of a patient from a
wheelchair to the examination table 10. Following receipt of the patient,
the lift mechanism 232 is configured to raise the patient and seat 28 so
that the top of the compartment 234 below the seat 28 is substantially
aligned with the top of the storage section 70 of the base 33. When in
this raised position, the seat back 26 may be reclined above the storage
section 70, providing a substantially flat examination surface between
the reclined seat back 26 and the seat 28.

[0119] Referring now to FIG. 27, the extension 44 is a first extension,
and the medical examination table 10 further includes a second extension
206. According to an exemplary embodiment, the extensions 44, 206 are
configured to be stored in the compartment 234 below the seat 28. In the
stored configuration (see FIG. 1), the first extension 44 at least
partially overlays the second extension 206, or vice versa. When in a
stored configuration, in at least one embodiment, the extensions 44, 206
are configured to fit within a volume of less than about one inch in
height by less than about two feet in length, by less than about two feet
in width, providing compact storage for efficient use of limited space.
The first extension 44 is further configured to project outward relative
to the seat 28 when in an extended configuration of the first extension
44. Projecting outward, the first extension 44 increases the length of
the medical examination table 10. In other embodiments, the first
extension 44 may be configured to project from a side of the examination
table 10. In still other contemplated embodiments, the first extension 44
may be hinged or pinned, allowing the first extension 44 to rotate and
project from either the end or the side of an associated examination
table.

[0120] According to an exemplary embodiment, the second extension 206 is
configured to project outward relative to the first extension 44 when in
an extended configuration of the second extension 206. In some
embodiments, the second extension 206 projects from an end of the first
extension 44, further increasing the length of the examination table 10.
In other contemplated embodiments, the second extension 206 projects from
a side of the first extension 44 (i.e., slides out sideways from the
first extension 44), providing additional tabletop surface, or is hinged
to project from either the end or a side of the first extension 44. In
some embodiments, the second extension 206 may be extended from the
compartment 234 while the first extension 44 is stored in the compartment
234, or vice versa. Such a configuration may, for example, facilitate the
examination of a patient of an intermediate height, or may provide
auxiliary tabletop space for placement of medical instruments.

[0121] According to an exemplary embodiment, configuring the first and
second extensions 44, 206 in the extended configurations elongates the
medical examination table 10 by a distance that is greater than an
internal dimension of the compartment 234, such as the length of the
compartment 234 or the width of the compartment 234. As such, the medical
examination table 10 is designed in a compact, space-efficient manner
that supports examinations of a wide variety of patients of differing
heights and physical limitations. As may be conducive for some medical
examination procedures, the medical examination table 10 may be
configured as a chair that may be adjusted for patients of differing
heights, or to facilitating transfer of a patient from a wheelchair.
Additionally, the medical examination table 10 may be configured as a
flat examination surface (e.g., table) that may be adjusted in length for
patients of differing heights.

[0122] Referring to FIGS. 27-29, the first extension 44 includes a first
surface 204 (e.g., substantially flat surface) having a portion 208 (FIG.
29) defined therein (e.g., opening, aperture) configured to receive a pan
202 (FIG. 28) positioned at least partially within the portion 208. A rim
210 of the pan 202 may be supported by the first surface 204 surrounding
the portion 208, allowing the pan 202 to collect debris, support liquids
or liquid-carrying items, and the like. In some embodiments, the pan 202
is easily removable and/or replaceable from the portion 208 of the first
extension 44 for quick cleaning or turnover of the medical examination
table 10. Pan 202 may be removable in the sense that a person of average
abilities can remove the pan without requiring a great amount of effort
or extra equipment. For example, a removable pan may be coupled to
portion 208 with an interference fit, force of gravity, one or more tab
and slot arrangements that can be readily released, or other similar
mechanism.

[0123] The first extension 44 may be formed from stamped and/or folded
sheet metal, molded from plastic, or otherwise formed. In some
embodiments, the folds and material of the first extension 44 allow the
first extension 44 to support the weight of a patient (e.g., a
distributed load of at least two hundred pounds) when in the extended
position. Likewise, the pan 202 may be formed from stamped metal, molded
plastic, or otherwise formed.

[0124] According to an exemplary embodiment, the first extension 44
further includes a first cushion 212 (e.g., cover, mat) removably
supported by the first surface 204 above the pan 202. The first cushion
212 may be attached to the first surface 204 by a releasable fastener,
such as suction cups, Velcro, tabs (e.g., "Christmas tree" clips)
extending from the underside of the first cushion 212 through holes 214
in the first surface 204, the weight of the first cushion 212 combined
with a higher-friction surface material on the first cushion 212, or
other fasteners. In some embodiments, the first cushion 212 is formed
from a flexible material (e.g., polymer) that is not permanently adhered
to the first surface 204. Removing the first cushion 212 from the first
surface 204 provides access to the pan 202. In other embodiment, the
first cushion 212 may be permanently adhered, but include an opening (not
shown) for accessing the pan 202 through the first cushion 212. In other
contemplated embodiments, the first cushion 212 is translatable on the
first extension 44, so as to be able to move to cover only part of the
pan 202. In one related application, the first cushion 212 may be
translated to partially uncover the pan 202 so that the cushion 212 still
supports a portion of a limb of a diabetic patient, and another portion
of the limb, such as a sore on the limb, may be washed and treated above
the pan 202 with water collecting in the pan 202. In still other
contemplated embodiments, a shorter first cushion may be configured to
only partially cover the pan 202, and the shorter cushion could be lifted
from the first extension 44 as necessary to remove the pan 202.

[0125] The first cushion 212 is intended to provide a comfortable surface
for the first extension 44 that may substantially match the texture and
feel of the seat 28 and seat back 26. As such, the surface of the first
cushion 212 may be formed from the same material and/or have the same
color(s) as the surfaces of the seat 28 and seat back 26. Without the
first cushion 212, the first extension 44 may otherwise draw heat from
the legs or feet of a patient, or become uncomfortable during a longer
examination. However, in some embodiments, the first extension 44 does
not include a cushion.

[0126] Referring to FIG. 29, the second extension includes a second
surface 218 (e.g., substantially flat surface) that is contoured along a
side 216 thereof to avoid interference with the pan 202 when the first
and second extensions 44, 206 are stored in the compartment 234. In some
embodiments, the side 216 is C-shaped. Contouring the side 216 of the
second surface 218 to fit the pan 202 allows for a greater length of the
second extension 206 to extend from the first extension 44, increasing
the overall length of the medical examination table 10 while the second
extension 206 is fully supported by the first extension 44.

[0127] According to an exemplary embodiment, the second extension 206
further includes a second cushion 220 (FIG. 27) removably fastened
thereto, such as by protrusions extending through holes 222 in the second
extension 206. In some embodiments, the second cushion 220 is not adhered
to the second surface 218, but is instead easily removable therefrom for
cleaning, replacement, or other purposes. The second cushion 220 may be
formed from the same material as the first cushion 212 in some
embodiments. In contemplated embodiments, the second cushion 220 is
translatable on the second extension 206, sliding to a different location
on the second extension 206.

[0128] The ability to increase the length of the medical examination table
10 by the first and second extensions 44, 206, allows for a more compact
table design, and also allows for the medical examination table 10 to
efficiently accommodate a greater range of patient heights. In some
embodiments, the second extension 206 is configured to support the weight
of a patient sitting or leaning thereon, such as being able to withstand
a distributed load of greater than one hundred pounds when in an extended
configuration in some embodiments. Further, in some embodiments, the
first extension 44 is configured to support a distributed load of at
least one hundred pounds over both the first and second extensions 44,
206 when the extensions 44, 206 are in the respective extended positions.
According to an exemplary embodiment, the stirrups 48 can be accessed and
used while the first and second extensions 44, 206 are extended.

[0129] According to an exemplary embodiment, the first extension 44 is
configured to translate relative to the seat 28 and the second extension
206 is configured to translate relative to the first extension 44. In
some embodiments, the first and/or second extensions 44, 206 slide
relative to the seat 28 and/or one another. In some such embodiments, the
second extension 206 includes a handle 224, such as a flange on the outer
end of the second extension 206. To extend the first and second
extensions 44, 206, an operator pulls the handle 224 and either the first
extension 44 pulls out first, the second extension 206 pulls out first,
or both extensions 44, 206 pull out of the compartment 234 together. In
some embodiments, greater friction is provided between the second
extension 206 and the first extension 44 than is provided between the
first extension 44 and the compartment 234 so that the first extension 44
pulls out before the second extension 206. In other embodiments, the
friction difference is reversed so that the second extension 206 pulls
out first.

[0130] In some embodiments, the second extension 206 slides through a rail
226 provided by a folded edge of the first extension 44. A low-friction
surface is provided between the first and second extensions 44, 206 along
the rail 226, such as ultra-high molecular tape. A protrusion 228 (e.g.,
acorn nut) from the underside of the second extension 206 is constrained
by a slot 230 (e.g., notch) in the rail 226 to prevent the second
extension 206 from being inadvertently pulled apart from the first
extension 44. The protrusion 228 may include a rubber bumper. In other
embodiments, relative tension in the rollers or other sliding elements
facilitates movement and controls which of the extensions 44, 206 pulls
out first.

[0131] While FIGS. 27-29 show the extensions 44, 206 integrated with the
medical examination table 10 of FIGS. 1-26, the extensions 44, 206 are
not limited to use with such tables, unless expressly provided in the
claims. In other embodiments, the extensions 44, 206 may be used with
examination tables having fixed surfaces, which may or may not lift
vertically. In some embodiments, the extensions 44, 206 may be used to
support the head of patient. In still other embodiments, extensions 44,
206 may be provided on more than one side of a medical examination table,
such as extensions corresponding to both lengthwise ends of such a table.

[0132] Referring now to FIGS. 4 and 30-32, the medical examination table
10, in some embodiments, includes the extensions 44, 206, which are
designed to be stored in close proximity with the stirrups 48. According
to an exemplary embodiment as shown in FIG. 4, the extensions 44, 206 and
the stirrups 48 are located in the front storage area 40 when in a first
configuration (e.g., storage configuration), and are designed to be
stored together without impeding movement of one another or the storage
bin 42. As shown in FIG. 30, the stirrups 48 are configured to be pulled
outward from the front storage area 40 without pulling out either or both
of the extensions 44, 206 from the front storage area 40, and vice versa.

[0133] Referring to FIG. 30, the stirrups 48 include a first beam 310
coupled to a second beam 312 by a joint 314 (e.g., pinned joint, pivot).
According to an exemplary embodiment, the first beam 310 is configured to
slide in and out of the front storage area 40, such as by way of a rail,
a track, a constrained pocket, or other guide structure. When stored in
the first configuration, the second beam 312 may be positioned over the
first beam 310 (or under), so that the overall length of the stirrups 48
is reduced sufficiently for the stirrups to fit lengthwise in the front
storage area 40. However, positioning the second beam 312 over the first
beam increases the overall height of the stirrups 48 for storage. As
such, the front storage area 40, in some embodiments, is designed with
sufficient vertical storage space to fit the stirrups 48 in the first
configuration.

[0134] Referring to FIG. 31, the stirrups 48 in the first configuration
are designed to closely fit within the front storage area below the
extensions 44, 206 when in the first configuration. In some embodiments,
the amount of vertical space T (e.g., tolerance, clearance) between the
stirrups 48 and the extensions 44, 206 is less than about three-eighths
of an inch, such as less than about a quarter of an inch. Designing the
stirrups 48 and extensions 44, 206 to closely fit with one another when
in the first configuration allows for a relatively large amount of
storage space in the removable storage bin 42, while allowing the seat
bottom 28, located above the front storage area 40, to be lowered to a
wheelchair accessible height.

[0135] Referring to FIG. 32, in a second configuration (e.g., operational
configuration) the stirrups 48 are extended from the front storage area
40 and rotated outward to facilitate medical examination. Although not
shown in FIG. 32, the second beam 312 may be rotated about the joint 314
to extend the length of the stirrups 48 in the second configuration. As
shown in FIG. 32, one or both of the extensions 44, 206 may be pulled out
from the front storage area 40 while the stirrups 48 are in a second
configuration (e.g., operational configuration). As such, the extensions
44, 206 are configured to serve as auxiliary table space during the
medical examination, supporting lower portions of the patient or medical
items. In some such embodiments, the extensions 44, 206 are configured to
support the weight of the patient when in the extended position, as
discussed above.

[0136] Referring to FIG. 33, a portion of a medical examination table is
shown according to an alternative embodiment. In this embodiment, a
cupped portion 3300 of stirrup 48 has a size and other configuration to
fit within an aperture 3302 defined by a surface of a handle 3324, a
surface of a second extension 3320, an inner surface of a wall 3304 of a
base, and an upper surface of a wall 3306 of a storage area 3340. Handle
3324 is disposed between stirrup 48 and a second stirrup opposite stirrup
48 (not shown in FIG. 33, but shown in an alternative embodiment in FIG.
30). Handle 3324 may be protrude about one half inch downward from second
extension 3320, or one half inch or less, or one inch or less in
alternative embodiments. An extension/retraction mechanism 3310 comprises
an arm 3311 movable within a slot 3313 to extend and retract stirrup 48
from a usage position to a stowed position. Mechanism 3310 may further
comprise a pivot device (not shown) configured to rotate arm 3311 outward
or inward over a range of angles.

[0137] Referring to FIG. 34, a portion of the medical examination table of
FIG. 33 is shown according to an illustrative embodiment. In this
drawing, stirrup 48 is shown extended a short distance by way of
extension/retraction mechanism 3310.

[0138] Referring now to FIG. 35, a portion of the medical examination
table of FIG. 33 is shown according to an illustrative embodiment. In
this embodiment, translation movement of first extension 3312 relative to
second extension 3320 is illustrated. A protruding surface 3315 is
implemented in this embodiment as an acorn nut coupled to a screw 3319
and a rubber washer 3317. The rubber washer 3317 acts as a stop or
interfering surface configured during retraction to contact surface 4401
to retract first extension 3312, and to contact surface 4400 during
extension to extend first extension 3312.

[0139] The acorn nut functions to hold rubber washer 3317 in place. The
acorn nut having protruding surface 3315 further acts as a spacer to
maintain a gap between the first and second extensions. The acorn nut
further acts as a wear guide for the sliding action of the second
extension against the first extension.

[0140]FIG. 36 illustrates a second acorn nut opposite the first acorn nut
having similar functionality.

[0141] According to one embodiment, a medical examination table comprises
a support structure. The table further comprises a first extension having
a first surface, a pan, and a portion defined in the first surface
configured to receive the pan, wherein the first extension is configured
to project outward relative to the support structure when in an extended
configuration of the first extension, elongating the medical examination
table. The table further comprises a second extension having a second
surface, wherein the second surface is contoured along a side thereof to
avoid interference with the pan, and wherein the second extension is
configured to project outward relative to the first extension when in an
extended configuration of the second extension, further elongating the
medical examination table.

[0142] According to another embodiment, the medical examination table may
comprise a first cushion removably supported by the first surface above
the pan such that removing the first cushion provides access to the pan.

[0143] According to another embodiment, the medical examination table
further comprises a base having drawers and a lift mechanism coupled to
the base, wherein the support structure comprises a seat that is
configured to be lowered relative to the base by the lift mechanism to a
wheelchair accessible height.

[0144] According to another embodiment, the first extension is configured
to translate relative to the seat and the second extension is configured
to translate relative to the first extension.

[0145] According to another embodiment, the medical examination table
further comprises a compartment below the seat, wherein the first
extension is configured to be stored in the compartment, and wherein the
second extension is configured to be stored in the compartment with the
first extension.

[0146] The construction and arrangement of the elements of the medical
examination table 10 as shown in the exemplary embodiment is illustrative
only. Although only a few embodiments of the present inventions have been
described in detail in this disclosure, those skilled in the art who
review this disclosure will readily appreciate that many modifications
